To all whom it may concern:

Be it known that I, Cums M. Lone, a citizen of the United States, and a resident of Napoleon, in the county of Henry, State of Ohio, have invented a certain new-and useful Motor- Attachment for Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to propelling means for vehicles, and particularly'to a motor attachment for bicycles, and has for its object the provision of a simple, light and improved attachment of this class, which is capable or"- being easily and quickly attached to a bicycle in operative relation'to one of the wheels thereof, preferably the front wheel, and of being adjusted in a simple and eiiicient manner by the operator, while riding on the bicycle, to engage the motor wheel with, or release it from, driving engagement with the vehicle wheel. Other objects and advantages of the invention will be apparent from the following detailed description thereof.

While the invention, in its broader aspect, is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings in which Figure l is a side elevation of the front end portion of the bicycle with the apparatus embodying the invention attached thereto, with the motor fly wheel removed. Fig. 2 is a front elevation thereof. Fig, 3 is an enlarged top plan view thereof with portions or the bicycle broken away, and Fig. i is a rear elevation of a ortion of the front fork of the bicycle wit v a part of the apparatus attached thereto. 7

Referring to the drawings, 1 designates a bicycle frame, having the front fork 2, and 3 the front wheel mounted in said fork.

A yoke lof inverted U-form and made in the present instance from angle iron, straddles the wheel 3 in advance of the fork 2, and has the lower ends of its legs fixed to, or supported by the respective ends of the front wheel axle 5 at the outer sides of the fork arms. It is'preferable to connect the yoke to the axle by projecting the axle ends through apertures in the yoke ends, and to then tighten the customary binding nuts on V the axle code without the yoke. or looped end of the yoke 4 is formed with The top a lateral horizontal extension 4 in the angle of which is fixedly mounted a'brac'ket 6 having the spaced ears 7, which are apertureol to form earings for the ends of a short shaft or pintle 8. An arm 9, adapted to support a small motor 10, is hinged at its forward end to the shaft or pintle 8 between the ears 7 and has its rear, endprovided with a threaded stud 11, which projects through a vertical elongated slot 12 in a bracket arm 13 and is clam ed in vertically adjusted position to said arm by a hand nut 14 threaded on to said stud. The bracket arm 13 is removably clamped to the adjacent side of the fork 2.

he motor 10, which is small and light in its construction and preferably of the single cylinder internal combustion engine type, is carried by the arm 9 for swingin movements therewith and has its crank short 15 proJected at one end over the wheel 3 and provided at such end with a friction.

drive wheel 16 adapted to be lowered into or raised from frictional driving engagement with the wheel periphery by verticalswinging movements of the bracket arm 9. The other end of the motor shaft is provided with a fly wheel 17. The operatlng fluid may be supplied to the motor from a tank 18 supported b the handle bars 19 or "from any other suita is source of supply.

It is evident that I have provided a siniple, light and inexpensive motor attachment for bicycles, which is capable of hem easily and quickly attached to the front rork of any bicycle, or removed therefrom, and of being adjusted by the operator from his seat on the bicycle to place the drive wheel 16 thereof into or out of engagement with the wheel periphery.

of numerous modifications and changes without departing from the spirit of the claims.
